Tonsilitis

Hi. I would like to ask lang po with regards to betadine gargle, since monday po kasi umatake yung tonsilitis ko. Ito lang po yung effective sakin. Safe po ba ito sa buntis? I'm currently on my 23rd week po. Thank you! PS. Hindi ko na po inask sa oby since this coming sunday may check up po ako, and ayoko po mapending yung check up ko kasi baka akala nya covid agad. Thank you
